The graph of crypto is fluctuating in 2021. So, it's very hard to say that which crypto will be profitable if you invest now. It's the right time for investors. However, I will mention some cryptocurrency names that is likely to be profitable to invest in.
1. XRP
2. DOGECOIN
3. TRON
4. Huobi Token
5. XLM
6. BCH
All of the tokens that you mentioned have a very big risk if invested, because the XRP token has collapsed and now the token is ranked 7 in the coinmarketcap which was previously ranked 4th, for Dogecoin and Tron tokens it seems like it's a little slow to move up after reaching its ATH earlier this month, so did the XLM token, and another for the BCH token which is still feasible and good to be chosen as an investment in 2021, the rest is not there, and only BNB is experiencing development which is good in the crypto market.
